"Still would like to know if the Plus buzzes when entering standby." There is a firmware update through the APP that now adds in this feature.
It does, or at least mine does, 'out of the box'. The 'buzz code' is different, although I suspect the app will let you change them further. Now
two buzzes at turn on and turn off. Still 3 when you make temperature. But now
one buzz for time out, and one buzz if you restart (remember, two on power up.....).
The unit is slightly bigger 'in all directions'. That is it's about .1 inches taller, wider and longer. The side profiles is about the same so there is a bigger 'flat top'. Nothing mechanical seems to interchange, including the buttons......the logo in the new one is 'backwards' (taller peak on the right), or maybe it's the original? It's also 20 grams or so heavier, 108 against 88 in my case. Really only noticeable if you have one in each hand I think.
The MP is much different (although they 'look alike'), it has a smaller metal tube that goes
inside the internal tube leading to the bowl, not outside it like before. And it's longer. It should stay in place better (not that I ever had a problem with the original). The top cover, OTOH, is not as secure. You can now very easily push it off from the sides (the new metal liner of the lid helps this, as does removing the 'peg and hole' of the original. This, I think, can be a problem. I have had it come open in a coat pocket once, not a happy thing. It comes with a heavy rubber band (complete with logo), but that strikes me as a PITA for routine use. Time will tell, but like the USB C connector an 'improvement' I'm not sold on yet.
The foll plate that makes up the bottom of the bowl has also changed. It now has a single ring of holes near the edge with 15 more tightly packed in the center (over the tube to the MP). My guess is this will give less restriction as the unit fouls in use?
There is definitely a bigger battery, it took much longer to 'top up' the half charge it came with and after several 'sessions' it's still showing 4/4 for battery level, something the original never did. Battery life would seem to be much improved.
IMO useful improvements in two key areas we asked for: warning on timeout and more battery life. I've yet to be convinced the port change is a step forward, I've got maybe 20 vapes, flashlights and whatnot that use mini or micro USBs, but this is the only USB C. While the charging cable it comes with is nice, I've ordered others since I don't always charge at the desk (I'll need another for the glove compartment and 'power bank' for field recharges). It's also important, I think, to have a second cable available to ward off 'funny cable issues'? The bowl cover being less secure is, by my experience, a negative. I've only had one accident (out of not too many uses), but when that happened I wished the lid was more secure, not less.
In the main, more positives than negatives I think. In the 'only have one' case, I'd go with the newer one to get the alert on time out and more battery life.
BTW, good old Randy at PIU didn't have to wait long to get my money when he offered the "VS20" code for a 20% discount Monday morning. Nor did he dally about, I jumped on it Monday when I got the good word and had in in hand Wednesday! Not sure how you beat that. A full charge/overcharge and I'm using it early Thursday.....
